The Agency would now contact all 2,443 affected vehicle owners individually as soon as possible to advise them on recheck options. Vouchers would be provided, it said.
"We are unaware of specific concerns relating to individual vehicles however, due to the poor quality of Mr Ah Wong's inspections there is a possibility that some vehicles may have been incorrectly passed. For this reason we strongly encourage people who have a current Warrant of Fitness issued by Mr Ah Wong to get their vehicle rechecked."
Just yesterday Auckland vehicle inspector - Elia Sipia and his organisation El's Auto Services in East Tamaki, Auckland - was also immediately suspended.
The Agency was also in the process of contacting 3783 of the company's clients to advise them on recheck options.
Six days ago the Agency warned 10,000 car owners around the country that their inspection might not have been properly checked.
